Dirty Bits: Praxis Bottom Bracket

Industry-wide, it seems that cranks with 24mm spindles remain the most common, but a good number of new frames come with oversized bottom brackets. Best known for their cold-forged chainrings, Praxis also offers a range of adaptor bottom brackets that allow you to run 24mm spindle Shimano, FSA and RaceFace cranks in BB30 and PF30 frames (it won’t work with SRAM/Truvativ 24mm GXP spindles though). With an emphasis on solid engineering, the shell is forged and machined from 7075 aluminium with an expanding collet design that locks it securely in place to avoid creaks, and issues with alignment and slippage. It also uses high quality stainless steel cartridge bearings with shield type quad-ring seals. Available for both road (68mm wide) and MTB (73mm wide) applications, the Praxis bottom bracket sells for $80.
